Please Help 2016 Z

Hey guys. So I am somewhat new to gen v. Tuned a lot of gen 3 and 4 stuff. Got all the books from the Tuning School and have been following them to the absolute best of my ability. But I am missing something here. Under hard load at high rpm the motor surges and bucks. The car has bolt ons in the form of an overdrive crank pulley a smaller blower pulley and a CAI. I have included a log from the car on the dyno and also the tune file that is in the car at the time of the log. Any help would be much appreciated.

My gen 5 tuning is limited, however from what I see your "predicted axle torque source" is driver. From my understanding that means its using the driver demand tables to identify how much torque you are requesting. With the car running more boost you are most likely hitting those targets sooner and its pulling timing to prevent it from making more torque. Increase your driver demand tables, but don't "rape them".
